SAN FRANCISCO (KCBS) – Most social networking websites are aimed at people staying in touch with friends, or re-connecting with people they haven’t seen or heard from in years.

But what if there are people in your life you would rather avoid?

A new app called Cloak can help, as it is billed as “incognito mode for real life.”

The iOS app uses Instagram and Foursquare to let users know where their friends and non-friends are at all times. As users log in to Foursquare and Instagram and check-in at a specific location, the app gathers that location data to give users the most up-to-date information on people in their social network.

Users can adjust the settings to determine what kind of distance you want to keep from people.

Developers of the app said they hope to add more social networks and features in the future.
